PCoIP 2nd display not refreshed for Xming Linux remote session.

Dear experts,

Here comes my issue. Since VDI is not supporting Linux Virtual desktop, I manage a Win7 one with Xming for accessing Linux. Works good for a single display approach. Not with 2.

Config :

Horizon View 6.0.2 - Basic Views Connection server install.

Zero client HP T310 - latest firmware - Dual screen (configured in 1280x960 each)

Virtual Desktop under Windows 7 64bits - Dual Display working fine for Windows apps. 2nd display in extended desktop mode.

Virtual Machine running Linux Red Hat 6.2 - 32bits - KDE desktop - (VM videocard set to 2 displays - with enough memory) - XDMCP protocol enabled under Linux.

I open a session via the View Connection serveur and I have access to my Windows 7 virtual destop with dual screen working fine. PcoIP tunnel, of course.

When, then, I start a Linux remote session via Xming (latest sourceforge version) from my Windows 7 virtual desktop, (via cmd xming : 0 -query "hostname"), It works fine for the main display. Good

If I move (entirely or partially) the Xming window to the 2nd display, the portion within the extended desktop area is not refreshed (while inputs via mouse work fine, but no rendering at all, except the Win7 window frame).

Why? Did I miss a configuration somewhere?

I have noticed the on KDE display configuration menu under my linux VM, that only 1 display is appearing. It this correct?

For info I have also tested Xming dual screen alternative (-screen 0 @1 -screen 1 @2) : same bug; Also tested 1 screen for large vitual display (2560*960) same bug on the 2nd display... I also have tested few engineering svga.XXX params, but with no success.

VMware and X11 experts, your help will be greatly appreciated!

Cyril.
